Ireland's 40% band starts at €44,000 — low by US standards. But if you weren't born to an Irish life, you may qualify for the remittance basis: foreign income stays untaxed in Ireland until you bring it in. For American and Canadian retirees, that one rule can change the entire math.
Last verified: 8 July 2026Ireland runs two rates. What changes is where the 40% starts:
| Status | 20% band (2026) | Above that |
|---|---|---|
| Single | Up to €44,000 | 40% |
| Married, one income | Up to €53,000 | 40% |
| Married, two incomes | Up to €88,000 combined (max €44,000 each) | 40% |
The Universal Social Charge applies on top of income tax, on nearly all income including foreign pensions once you're taxable on them. 2026 bands:
| Income slice | USC rate |
|---|---|
| First €12,012 | 0.5% |
| €12,013 – €28,700 | 2% |
| €28,701 – €70,044 | 3% |
| Above €70,044 | 8% |
No USC at all if total income is €13,000 or less. Over-70s with income up to €60,000 pay a maximum USC rate of 2%.
If you're Irish tax resident but not Irish domiciled — broadly, Ireland isn't your permanent home country of origin, which describes almost every American and Canadian mover — you pay Irish tax on Irish-source income, plus foreign income only to the extent you remit it to Ireland. It applies to foreign investment gains too.

| Keep filing? | Yes — the US taxes citizens on worldwide income wherever they live. Foreign tax credits offset most double tax; Irish rates are usually higher than US ones. | Generally no, once you cease Canadian tax residency — but watch the departure tax on deemed disposition of assets when you leave. |
| Treaty | US–Ireland income tax treaty (1997). How US Social Security is taxed for Irish residents is a known trap area — get cross-border advice before relying on any answer. | Canada–Ireland tax treaty in force; details of pension withholding vary by income type — verify for your case. |
| Social security | Totalization agreement in force since 1 September 1993 — no double contributions; work credits can combine. | Canada–Ireland social security agreement in force — CPP/OAS coordinate and export. |
| Accounts reporting | FBAR and FATCA rules follow you: Irish bank and brokerage accounts are reportable. | Standard CRA exit rules; final departure return in the year you leave. |
